[PATCH v3 12/26] powerpc: mpc85xx: Remove C29x support

[Bradley Morgan <brads@mainlining.org>]

No board in the tree selects ARCH_C29X, and the family lacks active
community maintenance. Remove the unused platform support and its
C29x specific crypto, clocking and SERDES setup.

Signed-off-by: Bradley Morgan <brads@mainlining.org>
